Description
Controls the fetch optimization mode of the TFDTable live data window mode.
Use the LiveWindowFastFirst property to set up the fetch optimization mode of the TFDTable Live Data Window mode.
If it is set to True, then FireDAC builds a query to return the first results as fast as possible. If it is set to False (the default value), then FireDAC minimizes the time to return all table rows.
Note: Setting LiveWindowFastFirst to True can be useful with the SQL Server and similar DB servers, which block the result set records, until the whole result set is fetched.
